I had conversations with 2 different CM's from different areas of the Park last weekend and they both said that Alladins Oasis is closed because Matt Ouimet is planning on bringing back the Tahitian Terrace.
One of them also said that he wants to:
1. Bring back the Skyway (including routing it to DCA after it leaves Tomorrowland, but that he's concerned about running the Skyway over the backstage area)
2. Turn the Fantasyland Skyway Chalet into a wedding chapel.
3. Bring back the PeopleMover by 2010.
4. Make some changes to Innoventions.
That should be enough grist for the rumor mill for a couple of days...
